Abstract: A transmission assembly for a ceiling-mounted TV in a vehicle has a series of gears mutually mated with each other so as to move the moving plate with respect of the fixing plate of the support. A biasing spring is added in between the series of gears so as to enable the transmission to be disengaged when the moving plate reaches a predetermined angle. A memory device is added to the transmission assembly to register the rotation angle of the moving plate and to shut down the power to the transmission assembly when the moving plate reaches a predetermined angle.

Abstract: A television stand has a base, a pivotal hinge extension formed on one end of the base and having a cavity defined therein, an extension formed in the base and laterally extending into the cavity, a pivot plate rotatably mounted on the extension with a vertical axis of rotation and a frame pivotally connected to the pivot plate with a lateral axis of rotation. Consequently, the frame can be folded into the base when the television mounted in the frame is not in use. In addition, the frame can be longitudinally rotated relative to the base to adjust the operation angle. The facility and versatility of using the television stand can be improved.
